COMPOSITION FOR STOPPING LEAKS IN HOT-WATER OIRCULATING SYSTEMS.

No Drawing.

This invention relates to novel means for stopping leaks in hot watercirculating systems, such as automobile radiators,- boilers, piping,sleam and hot water radiators, cylinder blocks in engines, pumps and thelike.

Heretofore it has been customary to introduce into hot water circulatingsyste1ns,and the like, a quantity of flaxseed meal and other vegetablesubstances, such as vegetable l cei'nent. The flaxseed meal and'othersubstances will circulate in 'the system. and will eventually find theirway to the leak, and become lodged in the same, and with the .aid of thecement and other vegetable substances will close the hole in the.system. The disadvantage of this vegetable composition is that thismatter sometimes lodges in some part of the system and clogs the same,while the cement and other vegetable substances will form a coating overthe interior surface of the circulatingsystem, and in the case 0automobile radiators will prevent the water from cooling when passedthe'rethrough. This renders it necessary to dismantle the radiator andclean the same before it is further used. These substances also have atendency-to crack after once being formed, thus causingthe leak to berenewed, also when the system is drained, the leak breaks forth anew,and the whole operation must I be repeated.

In my resent invention, I have provided a composition which, when onceformed to stop a leak, will become a permanent part of the system. Iattain this object by introducing into the hot water circulating systemav composition of powdered aluminum, flaxsee meal, sulphur and soap inabout the following proportions:

y Per cent- Powdered aluminum 15 Flaxseed meal 60 Sulphur 5 Soap 20 Thiscomposition is introduced into the hot water circulating system andmixes. with the water therein, and 1n passing by any leak in the systemwill be pulled into said leak by the flow of the Water. The flaxseedmeal contains linseed oil, and this and the soap acts as a carrier ofthe aluminum and other substances to the leak, will become lodged mini,sulphur and oxidized and close the leak by the building where theflaxseed mea in leak, and the alumi- Application filed June 10,

upv of the oxidized aluminum, and will result in a tough, fibrous,metallic patch over the leak which willv not be affected by jolts,-

or by draining the system.

The soap contained in the mixture acts as an agent for the suspension ofthe aluminum and flaxseed, the interior of the system. It also cleansesthe surface surroundingthe leak and causes the'oxidized aluminum topermanently cling to the surface which surrounds the leak.

No oneparticle of the flaxseed or aluminum is supposed to stop the leak,but the leak is gradually closed b a succession of particles of.aluminum oxi e being built up aroundthe leak, until the leak is closed.This does not ordinarilytake longerthan five minutes.

V The sulphur is added tothe composition, and acts as an insecticide tokill all germ life if in the flaxseed meal, and to cause the flaxseedmeal to remain fresh after being placed lnthe compound, and the sulphurforms with the linseed oil, such, as that which is present in theflaxseed meal, a rubbery .insoluble compound which hardens into aclinging, obstructive substance which aids in the stopping of leaks.That when the ingredients in the proportions specified, or in any nearratio to the proportions specified, are placed in the warm water in anautomobile radiator or other hot water circu-- lating system, the actionof the soap will be to form aluminum hydroxide which acts up on some ofthe free soap which is soluble, to form an insoluble soap.
